When I format the laptop, I delete the wireless driver. Now I install a new system ubuntu16.04, so the wifi couldn't open .
I search the hp support website, and found a issue. In the official support website, the wireless driver based on linux is :broadcom-wireless-18.104.22.168-6.71.x86_64.rpm, but the *.rpm file couldn't be installed to the ubuntu system directly, just only redhet system.
Alrough I transfered the *.rpm file to *.deb by alien tool, I also couldn't install the wireless driver, so need your help,thanks.
